Ford Sierra
The Ford Sierra's controversial 'jellymould' design gave way to a motorsport legend with the creation of the RS Cosworth. These turbocharged, wing-clad homologation specials are now prized collector cars for their Group A touring car dominance.

Ford Sierra Submodels
The Ford Sierra replaced the long-running Cortina in 1982, introducing a radical aerodynamic design that was initially polarizing. While base models were everyday family cars, the Sierra's legacy was cemented by its high-performance variants, particularly those developed with Cosworth. The three-door Sierra RS Cosworth, its homologation-special evolution the RS500, and the later four-door Sapphire Cosworth were built to dominate Group A motorsport, and they did.
Collectors almost exclusively seek out the performance models. The XR4i and XR4x4 offer a fun rear-wheel or all-wheel drive experience, but the turbocharged Cosworths are the main event. Their giant wings, aggressive styling, and touring car racing success make them icons of 1980s performance. A rich history of tuning and modification means finding a standard, well-preserved example is difficult and adds a significant premium.
The market for Sierras is almost entirely defined by the Cosworths. An average sale price of over $36,000 shows that pedestrian models rarely trade on the collector circuit. Pristine, low-mileage RS500s can command six-figure sums not reflected in this data set, while more common Sapphire Cosworths and modified cars make up the lower end of the enthusiast market.
Buying Tips
- Rust is the biggest enemy. Check thoroughly around the sills, jacking points, wheel arches, sunroof, and battery tray.
- For Cosworth models, verify its authenticity. Check that the VIN on the slam panel matches the V5 and the stamped number on the driver's side floor.
- The YB turbo engine is strong but requires care. Look for records of frequent oil changes and check for blue smoke on startup or acceleration, indicating worn turbo seals or piston rings.
- Many Sierras were modified. Originality commands a premium, so inspect for non-standard wheels, suspension, and engine tuning components.
- Interior plastics can be brittle and hard to find. Check the dashboard for cracks and ensure all electrical components are working correctly.
